CUTTER-HEAD.

SPECIFICATION forming part of Letters Patent No. 686,548, dated November 12, 1901.

Original application filed May 7, 1901, Serial No. 59,133. Divided and this application filed July 16, 1901. Serial No. 68,485- (No model.)

T0 on whom it may concern.-

Be it known that 1, CHARLES SEYMOUR, a citizen of the United States, and a resident of Defiance, in the county of Defiance and State of Ohio, have invented a new and Improved Cutter-Head, of which the following is a full, clear, and exact description, this being a division of the application for Letters Patent of the United States for a spoke-tenoning machine, Serial No. 59,133, filed by me on May '7, 1901.

The invention relates to woodworking machinery; and its object is to provide a new and improved cutter-head more especially designed for use on spoke-tenoning and similar machines and arranged to permit the operator to conveniently, quickly, and accurately adjust the several cutters and to securely hold the same in place to insure uniform work.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

A practical-embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a front face view of the improvement. Fig. 2 is a sectional side elevation of the same on the line 2 2 in Fig. 1. Fig. 3 is a rear face view of the same. Fig. 4 is a front elevation of one of the carriers for the mitercutter. Fig. 5 is an enlarged inner face view of the cam for adjusting the cutter-head. Fig. 6 is a plan view of the key-pinion for turning the cam and adjusting the miter-cutters. Fig. 7 is a side elevation of the spoke before forming the tenon, the point, and the miter; and Fig. 8 is alike view of the finished spoke.

The improved cutter-head illustrated in the drawings has a body G, which is essentially of disk form and integrally projects from a hub G, adapted to be secured in the usual manner to a revolving spindle. On the body G are mounted a set of tenon-cutters R, a set of miter-cutters R, a set of pointing-cutters R and a set of shoulder-cleaning cutters R all arranged in such a manner that when the end B of a spoke 13 passes between a pair of oatedin Figs. 1 and 2.

such revolving cu tter-heads then said spoke end is dressed and the tenon B, the point B the miters B and the shoulders B are all accurately formed at one operation.

Each set of cutters consists, preferably, of

two cutters, and the cutters R R R are mounted in the usual manner on the body G, while the miter-cutters R are each adjustably secured on the inclined top S of a carrier S by means of bolts R each carrier S being mounted to slide in guideways G formed radially on the face of the cutter-head body G A bolt S screwing in the carrier S and extending through an elongated slot G in the body G, serves to secure the carrier firmly in place after the carrier is adjusted in its guideways G On the face of each carrier S, at or near the inner end thereof, are formed segmental teeth S (s'eeFigs. 2 and 4) in mesh with a spiral rib S formed on the-inner face of a ringshaped cam S mounted to turn on the hub of the body G, the cam being held in position on the hub by a retaining-ring G as indi- The peripheral face of the cam S is provided with a gear-wheel S adapted to be engaged by a pinion S in the form of a key having a handle S (see Fig. 6,) adapted to be set in the body G. Then the key-pinion S is placed in position in one of the bearings G", it is in mesh with the gearwheel S and when the operator now turns the handle S then the pinion S imparts a rotary motion to the gear-wheel S and the cam S and causes the spiral rib S thereof to move the carriers S simultaneously inward or outward, according to the direction in which the key-pinion S is turned. Thus by the arrangement described the operator can move the carriers S, and consequently the miter-cutters R, outward or inward to cut the miters B the desired thickness. When the adjustment has been made, the operator simply removes the key-pinion S from the bearing G, it being understood that when the 9 adjustment has been finished and the bolts S screwed up then the several parts are securely locked in position on the cutter-head body G Having thus fully described my invention,

I claim as new and desire to secure by Letfers Patent- 1. A cutter-head, comprising a body having radial guideways, cutter-carriers mounted to slide therein, a cam mounted to turn on said body and having on its face a spiral cam engaging teeth on said carriers, a gear- Wheel on said cam, and a key-pinion removably held in a bearing in said body, to engage said gear-wheel, as set forth.

2. A cutter-head, comprisinga central body provided with radially-disposed guideways and with slots, radially-movable cutter-carriers slidably mounted in said guideways, a cam revolubly connected with said central 15 body and engaging said cutter-carriers for sliding the same, and bolts passing through said slots for securing said central body and said cutter-carriers rigidly together.

In testimony whereof I have signed my 20 name to this specification in the presence of two subscribing witnesses.

CHARLES SEYMOUR.
